Kevin Wolf 3dfa23b9ef vvfat: Fix array_remove_slice() 
array_remove_slice() calls array_roll() with array->next - 1 as the
destination index. This is only correct for count == 1, otherwise we're
writing past the end of the array. array->next - count would be correct.

However, this is the only place ever calling array_roll(), so this
rather complicated operation isn't even necessary.

Fix the problem and simplify the code by replacing it with a single
memmove() call. array_roll() can now be removed.
